Abstract
Abstract Microcapsules are widely used to add aroma to cigarettes and electronic cigarettes. However, at present, many cigarettes containing aroma microcapsules release insufficient aroma and the active ingredients cannot be fully released, which is due to the fact that the wall materials for preparing such microcapsules are mainly organic molecules, resulting in low thermal conductivity of such microcapsules. Moreover, these materials suffer from uneven distribution, low loading rate, uncontrollable preparation, etc., and has a limited effect on the thermal conductivity of microcapsules. In this study, aromatic and highly thermally conductive microcapsules were obtained by reaction using β-cyclodextrin as wall material and expanded graphite and menthol as core material. It was found that the thermal conductivity of the microcapsules increased exponentially with the increase in the amount of expandable graphite added, and this also indicates a gradual increase in the loading of the core material in the microcapsules. Further, the microcapsules have a high decomposition weight loss temperature, and there is no effect of using them in cigarettes and electronic cigarettes. Moreover, the microcapsules contain menthol, which can enhance the aroma of cigarettes.
